Rigid PCB
Rigid PCBs  are the backbone of electronic devices. Advancement in rigid circuit board technology has broadened the applications on electronic products ranging from computers, communication devices and consumer electronics to automotive and medical electronics.

Our in-depth experience in multi-layer, HDI and high-layer board design and manufacturing, including expertise in signal integrity and RoHS regulations, enables us to provide solutions aimed at speeding up the product development cycle.

 
Rigid PCB fabrication with Zitrok
Zitrok provides various sizes of Rigid Circuit boards, of different layers. All Rigid Circuits are tested with flying-probe testing machine or fixture-test tooling reflecting all Gerber data to insure continuity and other data requirements. We can turn your Rigid PCBs as fast as in 24 hours, depending on technologies.
